What industries would have used a shipment in a Philadelphia Quartz Company tank car?

Curious what industries would be receiving or shipping material in a Philadelphia Quartz Company tank car, and what that material would have been. Online info I found is not very specific on this point.

Thanks,

How about silicate of soda? Which, I gather, is also known as waterglass.

https://www.protocraft.com/category.cfm?ItemID=1170&Categoryid=36

The company slogan was "Mind your Ps & Qs" OK, not really.

The cars I have are lettered for Soluble Silicates:

Chances are the cars were used to bring raw materials to the PQ plant(s) rather than for shipping out finished product.

I'm waiting for the Philly Cheesesteak car to come by Dinner

Good Luck, Ed

Thanks, Ed! That makes sense. I saw two of those pages earlier but I hadn't picked out that it was all about the sodium silicates. But from your first link, I did a buncha reading about water glass and it was really informative -- even gave me some ideas.

Those are beautiful cars. Did they come lettered from a manufacturer or did you letter them yourself using the Protocraft decals?

If it were not for the fact that the air hoses were not connected I might have believed that these were prototype photos.

When I first started reading about model railroading in the early Sixties -- from material much older -- water glass was discussed as a common scenery material, for example in attaching ballast permanently or making 'real' coal loads.

Interesting, Overmod. Even more interesting that I've never even heard the term water glass and it appears to be a component in just about everything.

Thank you to the max, Maxman Yes I sure appreciate the positive support. 

I gotta get some weeds in there someday. Or did all the leaking soluble silicate kill them off Whistling

I'm pretty sure these were "vintage" Life-Like P2K kits. I'll bet there are still a few out there that haven't been built yet. Found a completed one here:

 I believe Bachmann also offered one in HO.
